Current research on metal-organic framework (MOF) luminescent sensing probes focuses on the design of three-dimensional bulk-sized MOFs that in return limits their up-close interactions with targeted guest molecules. In this work, we report a two-dimensional (2D) copper-based metal-organic framework, namely, AUBM-6, synthesized via solvothermal method from isonicotinic acid linker and copper(II) ion. The resulting 2D-layered MOF crystals were highly fluorescent in their exfoliated form and, therefore, explored for detecting several solvents, where a ratiometric selectivity was shown toward acetone. Metal ion sensing was also performed, by which fluorescent detection was observed to have the highest turn-off quenching efficiency toward Pd.
当前对金属有机框架（MOF）发光传感探针的研究主要集中在三维块状MOF的设计上，而这反过来限制了它们与目标客体分子的近距离相互作用。在这项工作中，我们报道了一种二维（2D）铜基金属有机框架，即AUBM-6，它是通过溶剂热法由异烟酸连接体和铜（II）离子合成的。所得的二维层状MOF晶体在剥离形式下具有高度荧光性，因此被用于检测几种溶剂，其中对丙酮表现出比率选择性。还进行了金属离子传感，观察到荧光检测对钯具有最高的关闭猝灭效率。
